A5932GESSR-T

Overview

The A5932GESSR-T is a three-phase sensorless sinusoidal fan motor controller and driver manufactured by Allegro MicroSystems. It utilizes NMOS technology to drive brushless DC (BLDC) motors in applications such as fan control. The device operates within a supply voltage range of 5.5V to 50V and supports surface mount installation in a 24-WFQFN package with an exposed pad, specifically sized as 24-QFN (4x4). It functions effectively across a wide ambient temperature range from -40°C to +105°C.

Feature Summary

Implements sensorless sinusoidal commutation for smooth three-phase BLDC motor operation
Integrates NMOS power stage technology for efficient half-bridge output configuration
Supports PWM interface for precise speed and direction management

Applications

Fan controller systems
Brushless DC (BLDC) motor drives
Three-phase motor motion control

Procurement Notes

Verify the specific suffix 'GESSR' against official Allegro documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 24-QFN (4x4) housing. Confirm that the sensorless control algorithm aligns with the intended motor load characteristics before finalizing procurement.

Selection Notes

Select this component when designing high-efficiency cooling solutions requiring silent, sinusoidal drive profiles without Hall sensors. It is suitable for systems demanding operation up to 50V and extended industrial temperature ranges. Consider the QFN package constraints for thermal dissipation requirements in dense layouts.

Part Context

This part belongs to the A5932 series of multi-phase motor drivers designed for advanced fan and pump applications. It represents an evolution in sensorless control technology, offering improved acoustic performance compared to standard trapezoidal drivers. The series focuses on reducing electromagnetic interference while maintaining robust torque delivery.
